摘要：

Limiting the short-circuit current effectively is of great importance to keep the safe and steady running of the power system. A novel fault current limiter (FCL) on the basis of a high speed switch and a triggered vacuum switch (TVS) is presented. The high speed switch is used to break the short-circuit current of the power system. The TVS is used to discharge the precharged pulse capacitor so as to rapidly extinguish the arc in the high speed switch and to realize the active transfer of the short-circuit current. A resistor is used to limit the short-circuit current. The parameters of the FCL for the 10 kV power system are designed and a FCL apparatus is fabricated. An onsite experiment of the FCL apparatus is performed in an actual transmission line of a substation. The FCL apparatus operates normally and achieves the expected current limiting effect.
